LEC magnetics has available isotropic plastic bonded magnets.

Isotropic bonded NdFeB materials can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. isotropic resin bonded Neodymium-Iron-Boron material offers a high energy product with an exceptional resistance to demagnetisation. Capable of operating up to 120ºC. Ring magnets may be machined from discs. Being isotropic, most shapes can be magnetised in any direction. Discs or rings may have either axial or diametric poles. Minimum field strength to magnetise to saturation is 3000kA/m (37500 0e). Such multipole fixtures may cost several thousands of dollars depending on design complexity and production rate requirements.

Hybrid magnets to create different magnetic properties, Multipoles Radial Bonded Magnet

With different ratio of additives to NdFeB powder, magnetic properties of hybrid NdFeB magnets can be tuned in a wide range. Once the ratio is fixed, magnetic property fluctuation can still be limited in a narrow bank. Hybrid magnets will meet customers' specified properties.

Characteristics for the initial magnetization of NdFeB bonded magnets

Rapidly quenched NdFeB powder used for bonded magnets is multi grain with grain size of sub-micron. Powder is isotropic in magnetic properties, which results in flat increasing of remanence and intrinsic coercivity with applied field. Magnet can only be magnetized to saturation in high fields.
